Many processes utilize roll forming machinery as a simple effective way to produce metal formed products.  Repeatable profiles and low cost per unit are some of the main advantages to rollforming.  When manufacturing highway guardrails, 2-space w beam guardrails or beams for highways using a quality roll former is important in producing quality parts.  Steel highway sign posts can also be made using a roll forming machine.  Many manufacturers of highway guardrails enjoy the cost benefits of manufacturing with a roll former versus a stamping or press machine.  Roll formers reduce the labor costs while increasing the overall part quality and operation throughput.

How can you tell what roll former is a quality one?

This is often a difficult question to answer.  Many companies claim to have quality roll formers at reduced prices.  As the old saying goes ‘you get what you pay for”.  An area that is often missed when evaluating the cost of a roll former is the cost of re-work, poor quality parts and unhappy customers.  These real costs must be added in to the overall calculation used when purchasing a roll forming system.  Companies like Samco Machinery have reputations as leaders in the industry.  They are equipment to handle any application regardless of how complex or standard it is.  Years of experience and a wide range of knowledge make them a valuable source in the industry.

So when buying a guardrail roll former I would start with the experts in the field.  Look for companies like Samco Machinery for solid understanding on how to do the job at a low cost with a high quality product.

Sheet metal workers in manufacturing plants make sheet metal parts for products such as stud and track framing, purlin, corrugated roofing and siding, and air-conditioning duct systems, trapezoidal roofs, automotive parts; and many other steel products. The work can be highly repetitive and labor intense. Sheet metal workers stand for long periods, lift heavy materials and finished products. The last thing they need is a manually operated press brake, requiring repetitive exertion with every bending operation.

How to manufacture better? Using a fully automated roll forming machine will increase quality, through-put and profit. They are more flexible, have a higher capacity, and are faster than other techniques for metal forming. They also reduce the overall number of operators and labors. Labor costs are cut dramatically and worker through-put. A roll forming machine reduces labor costs while increasing productivity. The use of rafted tools also allows for faster change over’s, as found on the Samco Machinery mills, and higher quality. This allows your business to manufacture more products in less time.

So, what do I need to look for in my next roll former machine?

• High quality product output.
• Rugged construction for long, trouble-free operation in heavy duty service.
• The ability to form continuous or pre-cut lengths repeatability without compromise in full-length or continuous feed operations accurately and economically.
• Hydraulic controls that index quickly and accurately.
• Dies that are quick and easy to change.
• The ability to perform a variety operations.
• A proven service record with years of experience.
• Replacement parts and optional components that are readily available.

When investigating a new roll former machine, make sure that you match the equipment to your requirements and obtain the highest quality product with appropriate features. Looking at only the cost can sometimes be deceiving, as versatility, productivity, efficiency of labor, and life cycle costs all need to be accounted for.

Goring Kerr was the Ford of the metal detection industry.  They invented the first industrial metal detection system for removing metal contaminants from the food processing environment.

Goring Kerr founded in 1947 by Bruce Goring Kerr and David Hiscock is well known as a pioneer and leader in the industrial metal detection field.  As the Ford of the industry Goring Kerr is well respected for their performance, quality and market leadership. Over the years Goring Kerr has gone through a number of transformations.  Currently the product range and brand is sold under the Thermo Fisher Scientific name.  They have also sold under the names Thermo Goring Kerr and Graseby Goring Kerr.

Metal detection systems are often used for inspection and automatic rejection of contaminated product during processing.  One of the most common places where metal detectors are utilized is in the free flowing bulk and powder steps of food production.  Here a metal detection systems is placed inline with the free flowing stream of product.  Typical products being inspected are grains, flour, sugar, filler product and more.  Typically these products are transported in a gravity feed part of the process allowing the raw ingredients to fall at the speed of gravity.  Typically this is a steady enough flow of product that a metal detection system can rely on its speed.  However, under many applications over time the flow of product no longer remains consistent over the days production.  This change in velocity of the free following product changes the way in which a metal detector performs.  Many metal detectors performance and overall sensitivity is based solely on laboratory testing and not ‘real world’ situations.  Another area that can cause a change in system performance is the automatic rejection or removal of contaminated product.  Typically in powdered product a gate or bell diverts the flow of product when metal is detected.  As the gate or flapper moves through the flow of product it can be slowed by the volume of product passing by.  This in turn changes how fast the metal detection system can react to a contaminant.  If you run over the rated amount of flow the system will become sluggish and slow.

So how do you test for gravity feed metal detectors performance?

Here are some tips for testing a gravity feed metal detection system.

1)      Test all products being inspected

2)      Test for minimum and maximum flows

3)      Test regularly throughout the production cycle

4)      Make sure the testing wand is rejected every time.

5)      Inspect rejected material in smaller metal detector and locate contaminant

These simple steps will help you in achieving a higher confidence level with the performance of your metal detector.

Do you need to replace or repair a conveyor belt on a metal detection system? When replacing a belt on conveyor systems you should pay attention to several key areas. The most important things to consider are the belt material and the belt splice. Metal detectors such as the Goring Kerr (Thermo), Safeline, Loma or Fortress Technology metal detectors are all impacted by these installation issues. Obviously you cannot use a metal zipper to connect the ends of the belt when used on a metal detection system. Equally important is the makeup of the belt. Many ‘colored’ belts contain pigments that interfere with most metal detectors.
